You cant win a SB with Alex Smith as your QB.
Many people have made this prediction, but the reaity is that with the brief appearance of Norv Turner for a season (and now Harbaugh) the 49ers have had a succession of crappy coaches and even hired that idiot from St. Louis' Super Bowl winning team...you know the guy that shortened, even more Warner's career.
Obviously, opposition is going to struggle to defeat Harbaugh's new/original version of the West Coast offense and during that time the 9ers should be able to eek out a SB victory or 3.
In any case the defense is one of the best in the league, and is already done some historic things. You just can't rush on them right now.
Thus-then that lessens the pressure on the secondary because teams have to be one-dimensional...especially if the lack of a running game puts them behind they will have to throw.
And the secondary did pretty good against "megadork"
